Walter;
The package that comes with Oracle, DBMS_LOB, has functions to Append,
Compare, Copy, Erase, GetLength, INSTR, LoadFromFile, Read, Substr, Trim,
and Write BLOBS. You should probably try starting from that one.
Oracle Built-In Packages from Oriely Press (ISBN 1-56592-375-8) Chapter 8,
Managing Large Objects.

I've been through the documentation on LOBs but am
still stuck trying to figure out how to interrogate
the contents of a BLOB.
We have a table with a BLOB column in it. All it
contains in text data (i.e. memo notes). Why it was
created as a BLOB and not a CLOB is unknown to me and
done before I was hired. All I need to do is determine
if a particular string ('.com') pattern exists in the
column, within the first 75 bytes, and return its
starting position.
Would someone help me out? Thanks!
